[JalexChen]

Checklist

• [x] All new jobs, commands, executors, parameters have descriptions
• [x] Examples have been added for any significant new features
• [x] README has been updated, if necessary

Motivation, issues

Helm 2 has been deprecated and no longer supported, therefore the tests and the commands associated with version 2 have been removed; helm 3's latest version is the default for commands now

Additionally, this was now migrated over to orb tools 11

Description
